ELT 204 - Introduction to Programmable Logic Controllers

Institution:

Delaware County Community College

Subject:

Electrical

Description:

This introductory course is intended to acquaint students in a hands-on mode with the basic skills and knowledge of programmable logic controllers, with respect to Industrial Systems. Students will learn to interpret electrical and Programmable Logic Controller (PLC) input/output diagrams and ladder logic. In addition, they will become acquainted with PLC functions, components, circuitry, testing of PLC programs and troubleshooting a PLC system. This course is recommended for students with little or no programmable logic controller experience. Upon successful completion of this course, students should be able to: Discuss terminology associated with PLCs; Describe the function, uses, and operation of a PLC; Define the function and operation of input/output diagrams and system networks; Interpret ladder logic to determine the functions of mechanical equipment; Discuss event driven sequencing as it relates to the input and output terminals of the PLC; Compare the operations of a PLC to manual and automatic control devices; Decipher which inputs and outputs are controlling internal counters and math functions; Interface wiring ladder logic diagrams with controller equipment; List the functions and types of timer instructions and give applications; Diagnose a PLC program, as it relates to a mechanical environment; Use PLC diagnostic equipment; Diagnose a motor control program in both manual and automatic modes; Analyze the consequences of changing a PLC program on the system being controlled; Identify the function and operation of a program interlock and give an application; Troubleshoot various levels of PLC systems to include up and down counter, timer and branching instructions.
